Nostalrius Begins - Quality wow vanilla realm (1.12)

I've got 3 friends who wish to play in this server with me. ( total 4 ppl in the party )

I want to know a good class combination that could get us into doing dungeons, without the problem of using the same type of loot.

I was thinking in rolling a pally, but everyone says they suck because buffbots and stuff, I would also like some explanation on that topic.

Thanks

Can i join you guys? Would be super fun!
